Blockage and swelling in your sinuses caused by viruses, bacteria or allergic reactions exerts pressure on your nasal linings leading to pain and headaches. Sinusitis simply means your sinuses are infected or inflamed, and this gives little indication of the misery and pain this condition can cause. When this condition repeats itself frequently with each
episode lasting for about 3 to 8 weeks, it is called chronic sinusitis.
Chronic sinusitis is commonly caused by Allergies or bacterial infection since they are the main sources of inflammation in the sinus membranes. When your nasal lings become irritated, they produce excessive mucus, leading to both post nasal drip and a runny nose. Other disorders that may cause post nasal drip are swallowing problems, vasomotor rhinitis, and inhalants (such as mol spores and dust).
Any condition that causes a weakened immune system or that causes chronic inflammation to the nasal mucous such as asthma or allergic disorders can also result in chronic sinusitis.
